Resource Guide: Nuclear Seismic Hazards


Nuclear power plants are built to withstand all environmental hazards, including earthquakes. As the debate continues in addressing the various costs of building secure and efficient power plants, the Forum on Energy has compiled a comprehensive Nuclear Seismic Hazards Resource Guide examining the policy, regulatory, technical and geopolitical aspects surrounding the seismic threat within public institutions and private industry. The guide identifies relevant and easy-to-understand online resources from governmental, academic, media and business entities both nationally and internationally. It includes:

  • Accurate news coverage
  • Informational graphics
  • Educational videos
  • Reports and publications
  • Online resources

Nuclear Seismic Hazards in the News

European Conference Focuses on Safety
At the POWER-GEN 2013 Conference in Vienna, presenters shared updates on nuclear reactor projects across Russia, Slovakia and Switzerland, according to an article in Power Engineering International. Professor Jukka Laaksonen, Vice President of Rosatom Overseas, said, “all new nuclear power plants under construction take into account the main safety issues that arose from Fukushima, including cooling of core without electrical power and the protection of the reactor containment integrity after potential core meltdowns.”

Taiwan’s Newest Plant and the Pacific ‘Ring of Fire’
Taiwanese residents debate whether to build the island’s fourth nuclear power plant near an active seismic fault. There is a possibility that safety concerns will shut down the plan and result in a loss of $9 billion that has already been invested by its national utility company, Taipower.

Mitigating Seismic Risk
In Eastern Tennessee’s Clinch River area, engineers are drilling core samples, documenting geologic, hydrologic, and seismic conditions—the initial step in plans to site the world’s first commercial small modular nuclear reactors (SMRs). Stakeholders, who argue that full-size nuclear power plants have a greater risk of seismic incidents or other disruptions, hope that the smaller scale of these SMRs will motivate reviewers to fast-track their approval and production. This process has also spawned a debate on the possibility of shrinking the ‘safety zones’ currently in place larger nuclear facilities.

Earthquakes Could Be Catastrophic for Iranian Nuclear Plants
A recent internal report by Iranian scientists warned government officials about possibly catastrophic consequences as a result of constructing nuclear plants in a seismically-active area. Despite these grim warnings, plans remain in place to add two more facilities at Bushehr — where an April 2011 earthquake struck — along with 16 additional reactors in other parts of the country.

The graph, at left, from the World Nuclear Association, shows the three major reactor accidents in the history of civil nuclear power — Three Mile Island, Chernobyl and Fukushima — in the context of over 14,500 cumulative reactor-years of commercial nuclear power operation.

The map below overlays a heatmap of 175,000 4.5+ magnitude earthquakes since 1973 based on data from the United States Geological Survey with worldwide locations of nuclear power stations, using information from the International Atomic Energy Agency. The map was originally created for and posted on a blog called maptd.com.

The chart below from the Center for Strategic and International Studies depicts the number of nuclear reactors (both in 2011 and an estimate for 2030) compared to ‘Seismic Density’ (the number of earthquakes/area in sq. km).

 The Federation of American Scientists also offers a compilation of maps comparing operating nuclear power plants with various variables, including existing North American faults and their geographical location vis-à-vis major American metropolitan areas, seismic hazards in terms of percent Gravitational Acceleration and various other hazard levels.
